I feel that the suggestions put forth are very dangerous, and I would not do anything of the sort.
The only safe way to lift a mast is with a crane. I don't care if it's 2 inches or 2 feet. Once stays are loosened, if something goes wrong its going to happen very quickly.
What if some moron in a power boat comes flying by with a huge wake while you're trying to use your neighbour's mast????
This reminds me of a guy I once saw who was about to hoist his kid aloft using a fender jury-rigged as a bosun's chair.
I told him that if he put his hand near the winch handle, I was going to deck him.
Don't take risks with these things. The consequences are not worth it.
Artboas, I do agree with you that a crane is the best way to work with a mast, but I do I think you qualify the suggestions I made as dangerous and compared them to hoisting a kid aloft on a fender only because you do not understand the geometry of the 34 mast and the fact that PGIJon only needs to release pinched wires.
1) The mast step is 1" 1/4 high, so you have to completely undo the shrouds and stays to be able to lift up completely clear of the step.
2) The spreaders are 30 degres swept-backed hence providing not only vertical support sideways from the shrouds but also vertical support towards the stern. In fact, on the 34, when the lower shrouds are tightened, the backstay doesn't even need to be attached and the mast is secured in position. Let me make it clear that one shouldn't sail without the backstay. The point simply is that the mast cannot topple over.
3) With the bottom of the mast still around the step, with its 3 shrouds on each side plus headstay (masthead) and backstay still attached, the mast cannot go anywhere.
4) If using another boat's mast or an outrigger from a shrimp boat, the mast is supported from above, the same way as it would be from a crane since the attachment point on the mast is the same.
Last but not least, it should be obvious to anyone that it must get done while protected within the confines of a marina, attached to a dock. This is not something you do in open waters so the chance of "some moron in a power boat flying by" should be non-existent.
Finally, in close to 60 years of sailing, having stepped and un-stepped dozens of masts every year on all kinds of boats from dinghies to 56 footers, I have seen more accident happen with "regular" cranes and no-experience marina jocks than when a few experienced sailors get together and do what I suggested.
